Fet's 3D Chess
You can’t switch to the other board and then don’t move on the other board. For example, if you have a queen on B1d1, you can’t move it to B2d1, only B2d2, B2e1, etc. Exception: if you capture a piece by switching boards. Then you can’t move on the other board, since you have captured a piece.
I feel like capturing a piece when changing board (i.e. : N1g2 —> Nx2g2). I think you shouldn't be able to switch boards if there is a piece there
Let’s start the game!
Board 1:

Board 2:

Would you like to be white? If so, then please tell your move.
Why is the second board empty ? Is it supposed to be like that ?
And also can the king change boards ? It would be too easy to avoid checkmate if it could
you know, I think you are onto something big, Fet. You should expect to hear from chess.com about them using your idea on their site. Its a REALLY good one, congrats.


[Piece abbrevation]+Board number]+[square coordinate].
Pieces can switch to the other board on the same square, and then on the same turn it can move on the other board. For example, a rook on B1e1 (board 1 e1) could go to B2e1 (board 2 e1), and then on the same turn from there move to B2e2 (board 2 e2). Important: you can only switch boards once per turn, and you have two choices when you move with a piece:
1. You move on the same board it was according to standard chess rules.
2. You switch boards and then move according to standard chess rules.
You can not move first on the same board you were and then switch boards. I reserve a spot for @GraysonKellogg, but if he doesn't want to play, anyone can play against me would'd like to.
